* Transmission lines should be 100 W differential traces. Vias and other transmission line discontinuities should be avoided. In order to meet the host TP1 output jitter and
TP4 jitter tolerance requirements it is recommended that the PHY has both transmitter pre-emphasis to equalize the transmitter traces and receiver equalization to equalize the
receiver traces. With appropriate transmitter pre-emphasis and receiver equalization, up to 8 dB of loss at 5 GHz can be tolerated.
** R5 and R6 are required when an Open Collector driver is used in place of CMOS or TTL drivers. 5 kW value is appropriate.
*** The value of R
